TUBE-MACHINE.

tain new and useful Improvements in Tube-- Machines, of which the following is a specification.

' This invention relates broadly toitube machines and more particularly to a machine of this character adapted to make tubes used in the manufacture of paper kegs, containers and the like.

The principal object of thisinvention is to provide a machine for producing tubes composed of superimposed layers of firmly united strips of paper or like material wrapped in spiral relation one upon the other.

A further object of this invention is to provide a machine for producing tubes of the character above described of varying diameters, from stripsof paper of uniform width. i

A further object of my invention is to provide an applicator, for applying an adhesive material to a strip of paper, and connecting the same with a guide roll so that the two may be moved inunison to change the direction of travel of the stigip of paper I with relation to the mandrel.

Another object of the invention is to provide winding belts mounted on frames which may be simultaneously or independently ad justed manually in accordance with the size of tube to be produced. I

Still another object of my invention is to provide an applicator frame made in two sections and having the upper section movable relatively to the lower section without "interfering with the travel of the paper therethrough.

A still further object of this invention is to provide a brake roll So disposed in the applicator frame that a uniform tension may be maintained on the paper passing therethrough. v

These objects together with attendant ad? vantages will in part be obvious and will in art be'pointcd out in' the specification hereinafter following and the drawings forming a part thereof throughout the several views of which like characters of reference have been used to indicate like parts. i

n'ecessary'that the strips be wound spirally,

the pitch 'of the spiral being dependent upon the diameterof tube to be produced, and the' width of the paper. In order that my machine may be utilized for the purpose'of producing tubes of varying diameters depending merely upon the capacity of the machine and the diameter of the mandrel employed, I have provided means for changing at will the mandrel, and the angle at which each individual strip approaches the mandrel to therebyv vary the pitch of the spiral and render it possible to make tubes having. diameters varying between comparatively wide limits, with the same b width paper. a

tube being made. This change may be accomplished in my machine by means of adjusting rods and hand-wheels connected thereto which permit simultaneous or independent adjustment of each of the winding frames. A

Referring more particularly to the drawings, the main frame of my tube machlne comprises a supporting base 1 mounted on a floor or platformfzl Adjacent one end of the machine there is provided a pair of standards 5 the upper ends 6 of whlch form bearings for the mandrel 7 upon whicht'he tubes are formed. These bearings are preferably formed in two parts to make removal and substitution of mandrels comparatively easy. When a smaller mandrel is employed, packing bushings are inserted, whlle f a larger-mandrel is used, part of the bushings are removed.

The paper strips for forming the tubes are fed from large rolls 8 rotatably mounted in racks 9 positioned at-each side of the machine. From all of these rolls, with the exception of the one supplying paper to applicator B, the paper passes through applicator frames where it receives a coating of adhesive material, and thence over suitable guide rolls to the mandrel. Ap-

plicator B, to be hereinafter described, supplies a coating of paraffin to the paper passing therethrough to prevent the same from sticking to themandrel. The applicators employed on opposite sides of the mandrel, while resembling each other in the general outline and function performed, differ in their. specific-embodiments. For the sake of-convenience I have designated the applicators shown on the right of the mandrel in the plan view by the reference character A, and the mandrels shown on the left by the reference character B. Since all of the applicators A, of which any number ay be employed depending only upon the thickness of the tube at is desired to produce, are alike in construction it will only be necessary to refer specifically to one which is shown particularly in Fig. 4 of the drawings. This applicator comprises an upper frame 10 pivotally secured to alower frame member 11 by the pivot 12 carried by the bracket members 14 projecting from the sides of the-upper and lower frame members respectively. Locking devices 15 areprovided for holding the frame in adjusted position. The purpose of the pivotal connection and the reason for its precise location will be apparent upon further describing the operation of the machine. The paper P passes transversely through each of the applicator frames, beneath the lower rolls 16 to the upper rolls 17 and thence around the brake rolls 18 to the guidevrolls hereinafter described. Each brake roll 18 is preferably provided with a flange 19 on One side thereof around which is positioned a brake band 20,-the ends of which are yieldingly forced together by a spring device 21, the tension of which may be varied at will is fed to the mandrel.

meager band may be secured as at 23 to the applicator frameto prevent the same from rotating with the brake roll. By means Off/i118 construction it is possible to maintain an even tension on the paper strip as the same During its passage around the brake rolls, the paper is brought into contact with a transfer or distributing roll 24 which receives a supply of adhesive material from a pick-up-roll 25 driven by a pulley 26, and journaled in such manner that a portion of its periphery is" immersed in the adhesive solution supplied to the pan 27 in the manner hereinafter to be described.

Each of the applicators Balso preferably comprises an upper frame member 28 pivotally connected to a lower frame member 29 by the pivot 30 located, in this instance, Within the sides of the frame. The upper frame .member may be held in its adjusted position with relation to the lower frame by means of set screws or equivalent locking devices 31. The paper supplied from the large roll passes around a lower roll 32 to an upper roll 34 and thence around the brake roll 35 which is provided with a tension mechanism 36 similarto those described in connection with the applicators A. I The paper from the brake roll passes beneath atop or press roll 37 to the guide rolls located adjacent the mandrel. During' its passage beneath the press roll the paper is brought into contact with a transfer or distributing roll 38 receiving a supply of adhesive material from the pick-u roll 39 driven by the belt pulley -10. With the exception of applicator B, the pick-up roll receives its supply of adhesive from the pan 41.

Applicator B may supply the paper with a paratlin coating from a bar of p'arafiin carried thereby, and traveling fromside to side of the applicator frame. The mechanism for accomplishing this is shown par- 110 ticularly in Figs. 9 to 11. As herein shown applicator B preferably comprises an upper frame member :28 pivotally mounted on the lower frame member 29 in a manner similar to the mounting of applicators B already .115 described. Transversely mounted between the side frames of the parailin applicator is a supporting bar 30' to which is pivotally secured the arm 31. The arm at its outer end preferably carries a bracket 32 in which 0 the holder 33 for the paraffin 34: is slidingly mounted on the rods 85, the paraflin being normally forced into yielding engagement with the paper strip by the sprin 's 36. The bar of paraffin may be readily re- 5 moved or adjusted as found necessary, by loosening the thumb nut 37.

The arm 31 may be oscillated so as to move the bar of paraffin transversely o'f the strip of paper as it pasSeS through the mashown 'in the drawingthis maybe accomplished by securing the pitman to any one 1 i of the openings 40, each of which is disposed at a different distance from the axis of rotation of the crank wheel.

Any suitable means for rotating the crank wheel may be provided such as a vertical shaft 4ldriven from the longitudinally extending shaft 100, through bevel gears 42;

z A clutch connection 43, may be employed to advantage, one of the members of which is movable into and out of operative engagement by the bell crank lever 44 working in the groove 45' and operable by throwing the pivoted handle 46 upwardly or downwardly. From the foregoing itwill be apparent that aJ-coating of paraflin may be applied to the surface of the strip of paper adapted to contact .with the mandrel and thus eliminate any tendency to stick. I

The transfer or distributing-"rolls of all of theapplicators are each mounted in a frame 42 pivotedponcentrically with the axis of rotation of the pick-up rolls so that during oscillatory movement of the frame, peripheral contact between the rolls may be maintained. The upper ends of theframe are provided with adjustable stops '44 adapted to control the distance between the transfer rolls and the brake rolls of applicators A, and the transfer rolls and the press rolls of applica- When it is desired to' tors B respectively. renew the paper in the applicators, .the frames 42, are swung against the rear stops 45 show n fin Fig. 4 so as to move the transfer the paper from applicators B passes underthe guide rolls, this'diflerence being necessitated by reason of the coating covering one side of each of the paper strips, with the exception of a. narrow central strip S on the paper passing through applicator A. This strip is adapted to overlie the joint formed in the pa'raflined layer lying next to the mandrel. This strip is left uncoated by providing a peripheral groove in the face of the transfer rollers or by making the rollers in two separate pieces suitably spaced one from the other. The guide rolls are rotatably journaled in brackets 47 having a pivotal connection 48 with supports 49 slidably For connecting the upper frame portions of the applicators to their respective guide rollS so that the two may be moved as a unit, there may be provided side bars 50 rigidly attached atone end to the applicator frame and reinforced throughout the length by cross arms 51. At their opposite endsthe side bars have a'pin and slot connection 52 with the brackets in which the guide rolls are journaled. These pin and slot connections accommodate for the change in distance between the pivots of the applicator frames 7 and the pivots of the guide roll brackets,

which change is caused by sliding the supports 49 along the base member. This adjustment may be accomplished by providing longitudinally extending rods 53 secured in any desired manner to the supports 49 through which they pass, and slidably mounted in a cross arm 54 at one end.- The rodsare preferably threaded at this end and provided with hand wheels 55 which'may be turned for advancing. or retracting the rods to simultaneously adjust [all of the' guide rolls. In order to permit individual adjustment of the guide rolls to accommodate for varyingthicknesses of the paper there may be provided handwheel turnbuckles 56 between each adjacent set of guide rolls. This sliding movement of the supports 49 is accomplished by a turning movement of the guide roll brackets on the pivots 48, and of the upper portions of the applicator frames onthe pivots 12 and 30 respectively.

It will be apparent that this turning movement of the upper portion of the applicator framesrelative to the lower supporting portions must not be accompanied by. any distortion of the paper passing therethrough overthe upper and lower rolls. It is forthis reason that thepivots of the applicator frames are positioned as close as possible to the line of travel of the paper. It has been found that within the limits of movement allowed, that theupper and lowerrolls are not materially displaced out of .alinement, and that the paper passes thereover freely in any position to whichthe frames may be adjusted. By placing the pivot outside or around the paper, the pivot center can be brought into exact line with the paper. For supplying adhesive in liquid formto the pans in which the picle'up rolls of the applicatorsrotate, there is provided a reservoir 57 adapted to contain silicate 'of soda or the like, and having a pipe line connection 58 with the respective pans of the applicators, with the exception of applicator B, which pans are in turn connected by cross pipes'59. The silicate of soda is forced from the reservoir and maintained in circulation by means of a pump 60. The liquid in each of the pans may be maintained at a constant level by providing stand pipes 61 forming overflow outlets therefor.

support the belt pulleys 67. Each of these carriages is adjustable toward and from the axis of rotation of the base by means of feed screws 68 passing through interiorly threaded blocks 69 secured to the carriages.

'Any form of operating means such as hand wheels 70 may be provided for operating the feed screws. The pulleys 67 are adapted to support and drive the winding belts 71, and the purpose of making the carriages adjustable is to provide a tension regulating means for the belts. For rotating the guide frames around the bushings 65 so as to change the spiral relationship existing between the belt and the mandrel around which they pass, there may be provided longitudinally extending rods 72 passing through the carriages 66 and journaled at their forward ends in the cross arm 54. The rods 72 may be secured to the parts 66 by providing collars on each side of the arms 66, or by forming a pivotal connection for the rods in each of said arms 66. Each of these rods is provided with an adjusting wheel 74 corresponding in function and operation to those described in connection with the adjusting rods 53. Individualadjustment of the winding frames is accomplished by turn buckles 75 such as clearly illustrated in Fig. 8 of the drawings.

, The driving mechanism for my improved machine comprises a longitudinally extending shaft 76 operatively driven from the motor 77 by means of a driving belt or sprocket 78. The rotation of the shaft may be governed through the medium of a clutch 79 and its controlling member 80. Secured on the shaft 76 adjacent each of the winding frames is a bevel gear 81 adapted to mesh with the gear 82 secured to the vertical jack shaft 84. Each of these jack shafts is rotatably mounted in the bushing 65 and carries on its upper end a driving pinion 85 for the gears 86 on the cross shafts 87. The cross shafts are preferably supported in bracket bearings 88 adjacent their central portions, and have their opposite ends passing through the bevel gears 89 which are provided with extensions journaled in the belt carriages. A slidable driving connection in the form of a key and slot 90 may be provided between the crossshafts and the bevel gears.- Each of the gears 89 is in mesh with the gears 91 on the pulley The winding frames are meager shafts 92. By reason of the particular form of driving connection itwill be apparent that the turning of the frame in no manner interferes with the continued operation of the machine.

The belt pulleys of the applicator frames, which have already been described, are also adapted to be driven by the motor 77.. This is accomplished by providing a belt 94 operatively driven from the shaft 7 6 and in turn transmitting power to the gear train 95, the last gear of which is in driving relation with the bevel gear 96. This gear drives the shaft 97 through the medium of gear 98 splined thereto, and which is in turn operatively connected to-longitudinally ex tending shafts 100 positioned beneath the applicator frames and receiving power through the bevel gears99. At suitable intervals on the shafts 100 are driving pulleys 101 adapted to alinc with and, constitute driving means for the belt pulleys 26 and 40 of the applicator frames A andB respectively.

From the foregoing description :taken in connection with the drawings it is believedthat the operation of the machine is obvious. This operation may be briefly summarized by stating that each strip of paper except f that through applicator B, passes from the supply roll through an applicator frame where it receives an adhesive coating on one side thereof and is then led to a mandrel around which it is wound and pressed into proper position by means of winding belts. When it is desired to change the diameter of the tubes made by the machine, and still employ paper of the same width, it is only necessary to insert a new mandrel in the bearings 6, and to adjust the angle of approach of the paper to such mandrel so that the pitch of the spiral in which it is wound thereon will be suitably decreased or increased. At the same time the winding belts are adjusted so as to act onthe paper at the most effective angle.
